MACHINE 'FOR MAKING BRIQUETS.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Application filed October 19, 1911. Serial No. 655,612.

To all whom. it mag/'concern Be it known that I, VcnAv SoUnK, a subjectof the Emperor' of Austria-Hungary, and resident of Mochov, Kingdom ofBohemia, Austro-Hungarian Empire, have invented'certain new and usefulImprovement-s in Machines for Making Briquets, of which the following isthe specification.

This invention relates to a machine for making horse food into briquets.

The object of the invention is to provide means for extracting themoisture from the product from which 4the briquets are formed, beforeand during the formation of t-he briquets.

A further object of the invention is to provide improved means forfeeding the material to the compressing mechanism, and also improvedmeans for compressing the briquets.

The invention also comprehends improvements in the details .ofconstruction and arrangement of partswhich will be hereinafter describedand particularly pointed out in the claims.

In the drawings: Figure 1 is a vertical central section of my improvedmachine.

Fig. 2 is a detail transverse section through the feeding trough. Fig. 3is a detail cross section taken through the feeding plunger Fig. 4 1s adetail vertical section o f the chute. Fig. 5 is a detail horizontalsection of the same.

1 indicates a trough semi-circular in cross section, and provided at itsbottom with a heating chamber 4, into which the hot air or steam isintroduced. Mounted in the trough are two spiral conveyers 2 2, suitablyrotated to carry the material from which the briquets are formed to thedelivery. open-ing 3. Communicating .with the top of the trough 1, arevent o emngs, over each of which is a casing 5. ach casing is providedwith a lateral opening 6, out of alinement with the vent openlng in thetrough, and directly under the opening 6 is formed a channel 7 withwhich a pipe 8 communicates.

Communicating with the delivery opening 3, is a chute 9, the lower endof which registers with a hopper 10 of a compressing mechanism. Belowthe hopper 10 is a horizontally disposed chamber 13 surrounded by aheating chamber 24, into which heated air 0r steam may be introduced.

Extending Iat an angle from the hopper 10, is a guide in which recirocates a plunger 11. At the bottom of) the guide 11 and on the oppositesides thereof are shoulders 15-15, the surfaces of which are hori-`zontal andare approximately on the plane with the upper part of thechamber 13. The

lower end of the plunger 11 is formed with two projecting flanges 12-12,which oper` ate on'the inner surfaces of the walls of the chute 9. Theactive end 12" of the plunger 12 is above the lower edges of the flanges12 and is disposed at right angles to the anguthe plunger '11. The otherarm of the bell crank lever 22X is pivoted to a link 21, the

lower end of which is pivoted to the rear end of the plunger 14, 'as at20. By this construction the-plunger 14 is moved toward the rear, whilethe plunger 11 is moved downwardly into the ho per 10 to force ay chargeof material into t e chamber 13.

The plungers 11 and 14 are operated by an eccentric 17, mounted on ashaft 16, the latter being rotated by any suitable means. A link 19 ispivoted at one end to an extension of the eccentric and its opposite endis pivoted to the plunger 1 4. Pivoted on the opposite side of theextension of the eccentr1c yoke, is pivoted one end of a lever 18,y

the opposite end of which is pivoted to the frame of the machine inalinement with the pivotal connection between lever 19 and the plunger14. The levers 18 and 19 act as a toggle connection so that when theeccentric is rotated the plungers will be reciprocated.

In'operation the material from which the briquets are to be iformed isintroduced to the trough 1. and is fed forward to the opening 3 by theconveyers 2; The material While in the trough is subjected to the heatfrom the chamber 4,'and-the moisture is extracted. The vapor from thematerial rises and passes through the vent openings and isv -lardisposition of the guide so as to properly deflected through the exitopenings 6. To

avoid the condensed vapor being returned to the material the channels 7are provided. The condensation accumulates in the troughs 7 and passesoff through the pipes 8, thereger 11 and also in the chamber 13. Then upon the rotation of the shaft 16, the charge in the 4chamber 13 will becompressed into briquets.. When the plunger -14 `is withdrawn theplunger 11 is simultaneously driven down to introduce another charge tothe chamber 13 so that the operation of feeding a deinite charge to thechamber and the forming of a briquet takes'place continuously. i

rlhe function of the projections 12 is two fold. When the plunger .l1 isforced down' the projections confine the material, so that the active orplunger-.surface 125L will have direct contact Iwith the materialthereunder. The second function performed by the projections and theshoulders 15, is that in case any of the. parts should break themovement of plunger 11 will be stopped by the shoulders and therebyprevented from accidentally falling into vthe path of the reciproca tionof the plunger 14. y l

` lt may be noted 'at this time that when the plunger 11 is raised, thematerial falls below the end 12a and also as the plunger 11i is beingwithdraw-n, said material will also fall into the chamber 13. Now whenthe plunger' 1l* is 'lowered it preliminarily compresses thecharge-which tends to hold itin block form in said chamber. Hence thecharge will better resist the force of thc plunger 14 and will notcrumble.

The briquets while formed in a continuous strip, may readily beseparated as each briquet is formed by ya single charge and is simplyheld to the adjacent briquet by adhesion. The'heated condition of thebriquets at the time they are formed serves to cause the particles v ofmaterial to more readily adhereto each other and thereby a homogeneousmass is produced. By means of the 4dry condition of the material, whenthe plungers are reciprocated, dust will rise and in order that it maynot become lmixed with the product, .l provide a vent opening 27 in theside of the hopper 10.

Briquets formed by amachine of the kind described retain all kthenutritive qualities of the food, and as practically all the moisture isremoved the material will not deterlorate.

' What I claim is:

1. vIn a machine of the class described, the combination .of a -chuteahorizontal chamber communicatingwith the chute, a lplunger operating insaid chamber, an inclined i e plunger operatmg in the chute ,to forcematerial iii-said chamber,`linksconnecting the two. plungers wherebywhenoneY of .said

plungers' vis withdrawn, the other will be forced forward in operativeposition, and means for operating the plungers.

2. ln a machine ofthe. class described, the combination of feeding meansincluding a chute, an inclined hollow-guideway, communicating with thechute, a chamber communicating with the inclined hollow ,guideway, aplunger operating inthe chamber, a plunger operating in the chute abovethe chamber, means connecting the plungers to cause themto operate inopposite directions, whereby to feed a charge vto the chamber andsubsequently compress a said charge in the chamber, an eccentric, linksoperated by the eccentric, a support, the end of one of the links beingpivoted to one of the plungers, the other of said links being pivoted tothe support, and means for operating the eccentric.

3. ln a machine of the class described, the combination of a trough, achute communieating with the trough, an inclined plunger at the bottomot the chute, said inclined plunger having spaced projections at itslower end to form with the chute a pocket, a chamber communicating withthe chute below the inclined plunger, a plunger operciprocate same,means for heating the ciamber, and means iorlfee'ding the material tothe chute.

5. ln a machine ot the class described, the combination of the chute, anlinclined plunger operating in the bottom of the chute,A a chambercommunicating with the chute below they inclined .-plun er, a horizontalplun- .ger operating in the c amber, a'shaft, a bell crank lever on theshaft, links connecting the bell crank lever and the two plungerS,

v whereby to simultaneously operate same, an

eccentric, and :toggle levers connected with one of the Aplungers andoperated by the eccentric lto impart motion to the plungers.

In testimony whereof I alli-x my signature in presence of two witnesses.
